Exchange Server - Export-Mailbox - keyword search limit?

Asked By Clay

My environment is single domain, single forest, single Exchange 2007 SP1
server running all email services.
Question - Is there a limit to the number of keyword search terms you can
use when using the Export-Mailbox cmdlet?

Due to a legal action I need to export all email from our Exchange 2007
server that has certain keywords.  I have figured out how to do this using
Exchange management shell, the export-mailbox cmdlet, and
the -contentkeywords filter.  I have successfully ran several test exports
using this filter with up to 15 or 20 keywords specified.   However I need
to search for about 700 keywords at once.  When I try to query with several
hundred terms though it always errors out.   I have formatted this command
into a ps1 script and when I view the resulting xml (log) file it looks
correct.

Here is the actual script I am using minus about 700 keywords.
Export-Mailbox -identity bmiller -Baditemlimit 1000 -Targetfolder
("810-99","63717-810-99","810-01","63717-810-01","040-05","63717-040-05","040-99","etc",

I do not believe it is a permissions issue because it will run fine if I
limit the keywords.  But if I put 200+ it always errors out.  I do not know
if there is a limit on the number of keywords you can use or if I have
something formatted wrong in my list.
Any help is much appreciated.

Any other thoughts on how to approach my issue?   I just need to search the
all mailboxes against a long list of search terms.

Why not run multiple exports?

That should work to get the data exported.  It may take considerably longer
(depending on the limit of the keyword search) but that may be my only
option.

If I was able to do the search with all terms I would end up with one
mailbox with a folder for each user in my DB with all relevant messages to
the search inside that folder.

If I run multiple searches (lets say 10) then I will end up with ten folders
for each person (each of these folders will contain each users mailbox
folder heirarchy underneath).  Any suggestion how to consolidate these down
to one folder per person?   Is there a switch I can use to re-export all
messages to a single folder?
